MAINTENANCE

At least once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer.

Follow the maintenance schedule in this manual.

BEFORE EACH USE

1.Check engine oil level.

2.Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See “LUBRICATION CHART”).

IMPORTANT: DO NOT OIL OR GREASE PLASTIC WHEEL BEARINGS. VISCOUS LUBRICANTS WILL ATTRACT DUST AND DIRT THAT WILL SHORTEN THE LIFE OF THE SELF- LUBRICATING BEARINGS. IF YOU FEEL THEY MUST BE LUBRICATED, USE ONLY A DRY, POWDERED GRAPHITE TYPE LUBRICANT SPARINGLY.

Always observe safety rules when performing any main- tenance.

TIRES

Keep tires free of gasoline, oil, or insect control chem- icals which can harm rubber.

Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

DRIVE WHEELS

Check front drive wheels each time before you mow to be sure they move freely.

The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels.

1.Remove hubcaps, locknuts and washers.

2.Remove wheels from wheel adjusters.

3.Remove any trash or grass cuttings from inside the dust cover, pinion and/or drive wheel gear teeth.

4.Put wheels back in place.

NOTE: If after cleaning, the drive wheels do not turn freely, contact a qualified service center.
